And now to go completely school tv. Hooray! I enjoyed this one.
This is actually something my flatmate made me do when I got very stuck with drawing cats, while I was developing characters for "There are Cats in this Book". It got me to interact with the characters as creatures rather than just drawings, and so get to know them. I've been drawing sheets like this one ever since, in varying degrees of finished-ness.
I still repeat poses, like outstretched arms, crouching on the floor and throwing tantrums... hey, well, better than always just standing around.
Mind you, a bit of standing-around is needed, because if you really know how someone stands around, you already know a lot about what they are like otherwise. But it easily happens that a sketchbook just becomes filled with a load of people waiting for... what? The bus? Waiting for you to finish the drawing, most likely. Well, let them try and stand around doing nothing while squished into a weird shape. Ha!
I might post some more tricks I've come across some other day, this is fun!
